Justification:
Listed as Endangered because its extent of occurrence is less than 5,000 km², all individuals are in a single location where populations are severely fragmented, and there is continuing decline in the extent and quality of habitat (conversion to manioc). The species continues to be persecuted as an agricultural pest.

This species occurs in eastern Paraguay, in Ñembucú and Misiones Provinces. The range is restricted by the Paraguay River to the west and the Parana River to the south (Woods and Kilpatrick, 2005). It occurs to the east of the city of Pilar (Bidau pers. comm.).
